CLOCK-ARBOR, 6C.

SPECIFICATION forming part of Letters Patent No. 769,559, dated September 6, 1904.

Application filed March 18, 1903.

To all whom t may concern:

Be it known that I, THoMAs W. R. MCCABE, a citizen of the United States of America, residing at `Winsted, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Clock- Arbors, Sac., of which the follovvingis a specication.

The object of my invention is to produce a device of the class speciied having features of novelty and advantage, and especially a construction which can be manufactured and assembled at a very loW cost.

In the accompanying drawings, Figure l is a vievv of the device assembled. Fig. 2 is a view similar to Fig. l, but with parts in section. Fig. 3 is an end view of Fig. l. Fig. 4 is a detail of the ratchet.

In the drawings, c denotes the arbor; o, a sleeve mounted thereon. This sleeve may be integral with the arbor, but preferably is a separate piece driven thereon and secured in place in any desirable manner. The sleeve has a shoulder c and a reduced portion d, which is grooved lengthwise, as at e. In ordinary practice the arbor is turned up from a steel wire and the sleeve is turned up from brass and driven onto and secured to the arbor.

f is a ratchet, preferably stampedv from sheet metal, pierced centrally, as at g, to fit upon the reduced portion CZ of the sleeve and having the projection c adapted to fit into the groove e and lock the ratchet to the groove.

In assembling the device the ratchet is Serial No. 148,345. (No model.)

forced into the sleeve, its projection engaging the groove e. A wheel of the time-train (indicated at m) is then put in place and the parts held in position by the spring n.

In the manufacture of clocks of cheaper grades this construction is of great advantage, as it means a great saving in the metal from which the sleeve and ratchet are made. It is readily assembled and from a mechanical point of view is entirely practical.

I claim as my invention-w l. A device of the character described comprising an arbor, a sleeve mounted thereon, said sleeve being provided with a shoulder, a groove formed in the sleeve beyond said shoulder, and a ratchet-wheel carried by said arbor and formed with a projection adapted to engage with said groove, substantially as described.

2. A device of the character described, comprising an arbor, a sleeve mounted thereon, said sleeve being provided with an outwardlyextending shoulder, a reduced portion formed beyond said shoulder, a ratchet-wheel carried by the arbor and locked in the said reduced portion and resilient means for holding the said ratchet-wheel against the shoulder, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses. v

THOMAS W. R. MCCABE.
